scope note
  • Any of several organic compounds composed of carbon, fluorine, chlorine, and hydrogen. Developed during the 1930s and manufactured under the trade name Freon, CFCs found wide application after World War II as aerosol-spray propellants, refrigerants, solvents, and foam-blowing agents. CFCs have been found to pose a serious environmental threat, greatly contributing to ozone depletion. In the stratosphere, the CFC molecules are broken down by the action of solar ultraviolet radiation and release their constituent chlorine atoms. These then react with the ozone molecules, resulting in their removal. (en)
  • 多種由碳、氟、氯、氫組成的有機化合物中任何一種。發展於西元1930年代，以「氟利昂（Freon）」之商標名製造。氯氟化碳（簡稱CFC）在第二次世界大戰之後便被廣泛應用，做為氣溶噴霧推進劑、製冷劑、溶劑和發泡劑。氯氟化碳會對環境造成嚴重威脅，造成臭氧極大消耗。在平流層中，氟氯化碳分子經太陽紫外線輻射而分解，釋放氯原子成分。氯原子接著與臭氧分子作用，造成臭氧的移除。 (zh-hant)
